General Description
The Sentry® Level-Lenz sight level indicator offers a cost effective method for
process operators to confirm the level of liquid without disrupting the process
or flow. Sight level indicators provide a safe way for operators to visually monitor
liquid levels in closed loop sampling processes.
Sentry Level-Lenz sight level indicators are manufactured of quality materials and
safety tested to 150% of the rated pressure to assure long, dependable service at
economical prices. The Level-Lenz has threaded process connections, two viewing
windows, and a body of 316 stainless steel. The Level-Lenz has a double window,
one on the front and one on the side. The operator can flash light through the side
window to enhance visibility. The level indicator can be used for hydrocarbon and
water-based liquids.
